I'd like to make a command that works like this: :KeepCursor cmd will the given execute ex command string, then restore the cursor's position. A primary example is:



:KeepCursor normal! *


which would perform a keyword search without jumping to the next match. This can of course be accomplished in other ways, but it's a good demonstration of the functionality I'm looking for, which I want to work in every possible case.



This is my attempt so far. I'm using feedkeys+imtx because I'd like the command to behave exactly as though I typed it. I put the cursor restoration in a finally so it works even if the command encounters an error.



function! s:keepcursor(qargs)
let l:view = winsaveview()
let l:winid = win_getid()
try
call feedkeys(':'.a:qargs."<cr>", 'imtx')
finally
if win_getid() != l:winid
if !win_id2win(l:winid)
return
endif
call win_gotoid(l:winid)
endif
call winrestview(l:view)
endtry
endfunction

command! -nargs=* KeepCursor call s:keepcursor(<q-args>)


However, it does not seem to work. Using :KeepCursor normal! * prints the search string but does not highlight anything. Running :hlsearch afterwards highlights the wrong thing.



My questions are a) can it be explained why this doesn't work and b) can such a :KeepCursor command be written?

          There is a lot going on here. I haven't debugged anything, but my guess is feedkeys() is part of your problem. I typically avoid feedkeys() as it is often easier to debug other methods.
